class_docstr: Object returned by the HB_master.run function
  
  This class offers a simple API to access the information from
  a Hyperband run.
docstr: extracts all learning curves from all run configurations
  
  Parameters
  ----------
          lc_extractor: callable
                  a function to return a list of learning_curves.
                  defaults to hpbanster.HB_result.extract_HP_learning_curves
          config_ids: list of valid config ids
                  if only a subset of the config ids is wanted
  
  Returns
  -------
          dict
                  a dictionary with the config_ids as keys and the
                  learning curves as values
